Answer:
D.(1,1)
Explanation:
Just plug in each pair of values in the multiple choice answers for x and y.
If we plug in (1,1)
The equation is
4(1) +5(1) ≤ 20
4+5≤ 20
9≤ 20
Since 9 is less than 20 we know statement is true, so we know (1,1) is a solution.
If we were to plug in any other choice like (0,5), the right side of the equation would be greater than 20 and the statement would not be true.
